ABSTRACT

Network pharmacological approaches were used to predict the components, targets and pathways of Erhuang decoction (EhD) in the treatment of acute lung injury (ALI). The SwissTargetPrediction platform, DisGeNET, Therapeutic Target Database (TTD), GeneCards and Online Mendelian Inheritance in Man (OMIM) databases were used to predict potential targets of EhD and were integrated with the predicted targets for the treatment of ALI. A protein-protein interaction network model was constructed by using String database and Cytoscape software; the DAVID platform was used for Gene Ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis. A network of drug components-targets-pathways was constructed by Cytoscape software and the SwissDock platform was used to dock the molecules of EhD found in blood with the key disease targets. An ALI model was established in mice and inflammatory factor detection and Western blot protein expression experiments with lung tissue sections were carried out to verify the effect of EhD in the treatment of ALI. Animal experiment ethical requirements were approved by the Ethical Committee Experimental Animal Center of Shandong University (Grant Number: 2016020). We identified 148 potential targets including signal transducer and activator of transcription 3 (STAT3), vascular endothelial cell growth factor A (VEGFA), RAC-alpha serine/threonine-protein kinase (AKT1), and nuclear factor-kappa B/p65 (RELA). The potential targets are largely associated with the biological processes of inflammation, oxidative stress, and apoptosis. Additional pathways relate to cancer, VEGF signaling, mitogen-activated protein kinase (MAPK) signaling, and Toll-like receptors (TLRs) signaling, along with other signaling pathways. Pharmacodynamic experiments showed that EhD could significantly reduce the content of inflammatory factors and the degree of lung injury of ALI mice. Western blot revealed that EhD could significantly decrease the expression of NF-κB/p65 and upregulate the expression of NF-kappa-B inhibitor alpha (IκBα). From the perspective of network pharmacology, the mechanisms of EhD in the treatment of ALI is consistent with the characteristics of multiple ingredients, multiple targets and multiple pathways. This research provides a reference for further study of the mechanism of this traditional Chinese medicine.

ABSTRACT

Objective: To study the molecular mechanisms of antioxidant effect and anti-inflammatory of water extract of Sophora flavescens (WSF) in lipopolysaccharide (LPS)-induced RAW264.7 cells. Methods: The optimum concentration of WSF was evaluated by CCK-8 assay. The inflammatory model was established with LPS by stimulating RAW264.7 cells in vitro. Then all cells were divided into control group, model group, WSF group and WSF control group. The levels of ROS and NO were analyzed with flow cytometry. Subsequently, the expression of iNOS, COX-2, Nrf2, and HO-1 was detected with qRT-PCR and Western blotting. Finally, the pro-inflammatory cytokines IL-6, TNF-α and anti-inflammatory cytokine IL-10 were detected by ELISA. Results: The CCK-8 assay revealed that 0.01 mg/mL WSF did not affect the cell viability. Compared with control group, the LPS-induced inflammatory response could significantly increase the production of NO and ROS, and the IL-6 and TNF-α were also significantly increased (P < 0.05, 0.01, and 0.001). Furthermore, the expression of iNOS and COX-2 were significantly increased (P < 0.01, 0.001), but the expression of Nrf2 and HO-1 were inhibited (P < 0.05). However, compared with model group, the WSF group not only significantly decreased the levels of NO, ROS, IL-6, and TNF-α, but also decreased the expression of iNOS and COX-2 (P < 0.05, 0.01, and 0.001). In contrast, the the level of IL-10 and the expression of Nrf2 and HO-1 were significantly increased (P < 0.05, 0.01, and 0.001). Conclusion: These results suggested that SF exerted protective effect against LPS-induced inflammatory and oxidative responses in RAW 264.7 cells by the activation of the Nrf2/HO-1 pathway.

ABSTRACT

Purpose To assess the frequency of discordances in ER, PR and HER-2 status between primary and recurrent cancer and the impact of the discordance on breast cancer patient survival. Method Immunohistochemistry and/or fluorescent in situ hybridization was used to evaluate ER, PR and HER-2 status of primary and recurrent cancer in 62 breast cancer patients. The correlation between discordances in ER, PR and HER-2 receptors and clinicopathologic characteristics and patient survival was analyzed. Results Among 62 patients with breast recurrent cancer, discordance rate for ER, PR, and HER-2 was found in 6 (9.7%), 9 (14.5%) and 3 (4.8%) patients, respectively. During the follow-up period the ER-discordant cases had a poorer overall survival (median 29 months vs 44 months, P=0.021) and post-recurrence survival (median 6 months vs 15 months, P=0.027), compared with the concordant cases. No impact on overall survival or post-recurrence survival was observed for PR and HER-2 discordance when compared with the respective concordant cases (P> 0.05 for all).Conclusion Our results demonstrate an evident change regarding ER, PR and HER-2 between breast primary and recurrent cancer, and the ER unstable status in breast cancer suggust a worse prognosis.

ABSTRACT

The traditional systemic treatment of post-traumatic stress disorder (PTSD) requires a long time period for an effect and has obvious side effects. In this study, tetrandrine temperature-sensitive gel (TTG) was prepared for treatment of PTSD in mice by nasal administration. TTG was prepared with poloxamer as matrix, the gelation temperature was suitable (<32 ℃) and the gelation time was short (1.32 min). Rheology experiments demonstrated that TTG has temperature sensitivity. In vivo imaging system of small animals proved that TTG nasal cavity retention time was so long. The cilia toxic test of toad showed that the formulation was safe. Animal experiments were approved by the Ethics Committee of Beijing Institute of Radiation Medicine, Academy of Military Medical Sciences and the experiments were conducted in accordance with relevant guidelines and regulations. The mice were randomly assigned into healthy group, model group and TTG group. The PTSD model of mice was established by single prolonged stress (SPS) and foot-shock method to generate anxiety and fear behavior. On the day 0 of TTG administration, SPS model mice were evaluated by the elevated plus maze (EPM). Percentages of open arm entries number (OE), latency of open arm entries (OL) and the residence time of open arm entries (OT) all indicated that the SPS model was successfully established. On the 7th day of TTG administration, TTG increased the OE and OT, decreased the OL of SPS mice. The feard behavior of mice in the foot-shock model was tested using conditioned fear box, 7 days of TTG treatment can reduce the freezing time of the mice obviously. The pathological changes of hippocampus, prefrontal cortex and amygdala were observed by H&E histological sections and c-fos immunohistochemical expression. The main influenced areas of PTSD were revealed to be the CA1 of hippocampus, prefrontal cortex and amygdala. All of the above indicated that TTG is a convenient, safe and effective drug for PTSD treatment, and will provide a new choice for clinical management of PTSD.

ABSTRACT

Topically applied traditional Chinese medicines (TCM) generally show low transdermal rates and doses, leading to weak therapeutic efficacy. Here, cataplasm of white mustard seed varnish was prepared. The effects of iontophoresis and sonophoresis on the transdermal delivery of this TCM and its anti-asthma effect were evaluated. Active components of white mustard seed, rhizoma corydalis and Radix Kansui were obtained after alcohol extraction, respectively. The volatile oil in Asarum Heterotropoides were obtained with volatile oil extraction equipment. The drug loading ratio of cataplasms was 17% (w/w). Franz cell diffusion method was used to evaluate the accumulated permeation amount and the steady-state transdermal absorption rate of sodium thiocyanate. The improvement of sonophoresis on transdermal absorption was higher than that of iontophoresis.Asthma model of guinea pigs were established. Cataplasms of white mustard seed varnish were applied on the back of guinea pigs. Iontophoresis and sonophoresis obviously promoted the transdermal absorption and enhanced anti-asthma efficacy of white mustard seed varnish cataplasms. Pathological analysis showed that iontophoresis and sonophoresis significantly alleviated inflammation. Compared with the model group, IL-4 and IgE levels in the cataplasm group, cataplasm/iontophoresis group, cataplasm/sonophoresis group decreased obviously, although the IFN-γ levels markedly increased. Moreover, the therapeutic efficacy of cataplasm/sonophoresis group was the best in all the groups, even leading to levels similar to that of healthy animals. Iontophoresis and sonophoresis are effective methods to promote transdermal absorption of cataplasms. Moreover, the effect of sonophoresis is higher than that of iontophoresis. Physical penetration improvement techniques provide a novel insight for the wide application of transdermal TCM.

ABSTRACT

OBJECTIVE: To meta-analytically compare combined transarterial chemoembolization (TACE) plus radiofrequency ablation (RFA) and surgical resection (SR) for the treatment of hepatocellular carcinoma (HCC) within the Milan criteria. MATERIALS AND METHODS: PubMed, Medline, Embase, and Cochrane Library were searched for studies comparing these two therapies that were published between January 2006 and August 2017. Overall survival rate (OS), recurrence-free survival rate (RFS), major complications and the average length of hospital stay were compared between these two therapies. Meta-analytic pooled odds ratio (OR) was calculated using TACE plus RFA as the base category. RESULTS: Seven case-control studies and one randomized trial were identified. Meta-analytic results revealed that, compared with SR, TACE plus RFA had significantly higher 1-year OS (OR for survival = 0.50, p = 0.009) and lower major complications (OR = 1.88, p = 0.02) after therapy. Three studies reported on the length of hospital stay. The average length ± standard deviation reported in individual studies for SR and TACE plus RFA groups was 19.8 ± 8.4 days and 7.4 ± 2.2 days, respectively; 18.7 ± 4.9 days and 11.5 ± 6.9 days, respectively; and 16.6 ± 6.7 days and 8.5 ± 4.1 days, respectively (p < 0.0001 for all studies). Three or 5-year OS and 1-, 3-, or 5-year RFS did not significantly differ between the two therapies. CONCLUSION: Combined TACE plus RFA may be an alternative to SR for the treatment of patients with HCC within Milan the criteria. Non-randomized design in most of the original studies was a limitation.

ABSTRACT

Objective To evaluate the value of serum CEA and CA19-9 concentration for clinical staging of colorectal cancer. Methods A total of 350 patients who underwent the surgical treatments for colorectal cancer between February 2015 to January 2017 were enrolled. The serum CEA and CA19-9 were detected by chemoluminescence method. Results The positive rate of CEA of patients in stageⅠto Ⅳ was 25.00%, 36.69%, 50.78% and 66.67%, respectively. The positive rate of CA19-9 of patients in stageⅠto Ⅳwas 2.94%, 10.07%, 17.97% and 53.33%, respectively. The positive rates of CEA and CA19-9 were gradually increased with the stage developing (P<0.05). Results from multivariate logistic regression analysis showed that the positive levels of CEA and CA19-9 were risk factors in the TNM staging of colorectal cancer. The ORs and 95%CI were 1.790 (1.163-2.755)and 3.476(1.790-6.749), respectively. Conclusion The positive serum concentrations of CEA and CA19-9 showed significant associations with TNM staging. Preoperative serum concentrations of CEA and CA 19-9 could be auxiliary diagnostic indicators to assess the condition of colorectal cancer.

ABSTRACT

AIM:To study the protective effect of heat shock factor1(HSF1) on the mice with lipopolysaccha-ride (LPS)-induced acute lung injury(ALI),and to screen the relevant differentially-expressed genes. METHODS:ALI mouse model was established by LPS intracheal instillation. The macroscopic and pathological changes of the lung tissue were observed,and the concentrations of total protein,TNF-α, IL-β, IL-6 and VEGF in the bronchoalveolar lavage fluid (BALF) were analyzed. Differentially-expressed genes in the lung tissues of HSF1 +/ +mice and HSF1 -/- mice with ALI induced by LPS were screened by gene chips. The key gene was verified by real-time qPCR. RESULTS:The macroscopic and pathological changes of the lung injury in HSF1 -/- +LPS mice were more serious than those in HSF1 +/ ++LPS mice.The concentrations of total protein,VEGF,TNF-α,IL-1β and IL-6 in the BALF of HSF1 -/- +LPS mice were significantly higher than those of HSF1 +/ ++LPS mice(P<0.05). Compared with the HSF1 +/ +mice,a total of 918 differentially-ex-pressed genes were indentified in the HSF1 -/- mice, among which the expression levels of 65 genes had obvious diffe-rence,with 28 genes up-regulated,including Atg7,ccr1,cxcr2,Tbl1xr1,Mmp9,Pparg,Plcb2,Arrb2,Cntn1,Col4a6, etc, and 37 genes down-regulated,including Fgfr1,Fgfr2,Map4k4,Ddx58,Tfg,Stat3,Smad4,Lamc1,Sdc3,etc. The results of real-time qPCR showed that the mRNA level of CXCR2 in HSF1 -/- + LPS mice was significantly higher than that in HSF1 +/ ++ LPS mice,which was consistent with the results of gene chips. CONCLUSION:HSF1 has protective effect on the mice with LPS-induced ALI. CXCR2 may be involved in the protective effect of HSF1 on this process.

ABSTRACT

Objective To explore the application and influencing factors of early clopidogrel use in patients with acute myocardial infarction (AMI) in the central-rural region of China in 2006 and 2011. Methods A representative sample of patients in central-rural region of China admitted to hospital for AMI was created from a two-stage random sampling. In the first phase,a simple random-sampling procedure was used to identify participating hospitals. In the second stage,we selected patients admitted to each participating hospitals for AMI with a systematic sampling approach. Then we obtained clinical information via central medical record abstraction for each patient. For analysis of early clopidogrel therapy (within 24 hours of admission) status,we used multilevel Logistical regression models with the use of generalized estimating equations. Results We identified 1464 patients eligible for early clopidogrel therapy. From 2006 to 2011,the early application rate of clopidogrel increased significantly,from 3.98% to 48.72% (P<0.0001). Logistic regression analysis showed that patients with hypertension were more likely to receive early clopidogrel(OR=1.65,95% CI=1.21-2.26,P=0.001),smokers were associated with greater likelihood to receive early clopidogrel(OR=1.87,95% CI=1.19-2.95,P=0.007),and patients with chest discomfort during hospitalization indicated association with higher likelihood of early clopidogrel use within 24 hours of admission (OR=2.17,95% CI=1.35-3.49,P=0.001). Conclusions Early clopidogrel use in AMI patients has been improved from 2006 to 2011. However,tremendous gap still exists between guidelines and clinical practice. Quality improvement initiatives are in urgent need to support further improvements in early clopidogrel use for AMI patients.

ABSTRACT

To study the in situ intestinal absorption kinetics and compatibility influence of peimine and peiminine in rats, the absorption of peimine and peiminine in small intestine (duodenum, jejunum and ileum) and colon of rats was investigated using in situ single-pass perfusion method and the drug content was measured by HPLC-ELSD. Perfusion rate, pH, concentration of drug, gender and bile duct ligation can significantly affect the absorption of peimine and peiminine, the Ka, and Papp values in the condition of pH 6.8 and pH 7.4 had significant difference (P<0.01), as drug concentration irlcreased, the absorption parameters of peimine and peiminine decreased, Ka and Papp between low concentrations and middle concentrations was significant difference (P<0.01). Verapamil can not affect Ka and Papp of peimine and peiminine which are in the extract (P> 0.05). Bitter almonds and licorice can significantly reduce the absorption of peimine and peiminine with the usual dose (P<0.01), extracted separately and together had no significant difference on Ka and Papp (P> 0.05). Experimental results show that the absorption features of peimine and peiminine are basically the same, both of them could be absorbed at all segments of the intestine in rats and had no special absorption window, and with significant differences between male and female individuals. The absorption of peimine and peiminine complies with the active transport and facilitated diffusion in the general intestinal segments. Bitter almond and licorice can reduce the intestinal absorption rate ofpeimine and peiminine.

ABSTRACT

<p><b>BACKGROUND</b>Long-term use of antiplatelet agents, statins, beta-blockers and angiotensin-converting enzyme inhibitors are proven therapies for secondary prevention in acute coronary syndrome. However, little is known of physicians' opinion about their use in China.</p><p><b>METHODS</b>In 2010, standard questionnaires were posted to chief cardiologists in 1397 geographically diverse and representative sample of tertiary and secondary hospitals in China, collecting information about their opinions on the recommended treatments for acute coronary syndrome.</p><p><b>RESULTS</b>A total of 1009 (72%) cardiologists responded with a valid questionnaire. Of them, 77% reported routine use of all the four main secondary preventive treatments, with little difference between secondary and tertiary hospitals (75% vs. 79%, P = 0.16). Of the cardiologists reporting routine or selective use of aspirin, beta-blockers, statins and angiotensin-converting enzyme inhibitors, 94%, 85%, 73% and 86% would recommend indefinite use respectively. For all the 4 treatments combined, only 63.5% reported indefinite use at the same time, with no significant difference between secondary and tertiary hospitals (62% vs. 65%, P = 0.17), nor between hospitals with or without fast track for primary percutaneous coronary intervention (66% vs. 61%, P = 0.50).</p><p><b>CONCLUSIONS</b>Although Chinese cardiologists seem well informed about the value of main secondary preventive treatments for acute coronary syndrome, there is still gap in their understanding of the need for combined and prolonged use of these treatments.</p>

<p><b>OBJECTIVE</b>To evaluate the effects of Artesunate on tumor necrosis factor alpha (TNF-alpha), monocyte chemoattractant protein (MCP-1), and on reduced activation normal T cell expressed and secreted (RANTES) in the serum and the synoviocyte culture supernate of collagen-induced arthritis (CIA) rats.</p><p><b>METHODS</b>Eighty male Wistar rats were selected to establish the CIA rat model. On the 6th day after modeling, 60 rats with the sum of arthritis index of right metapedes and two propodium > or = 6 were selected, and randomly divided into 6 groups (n = 10), i.e., the blank control group, the CIA model control group (treated with normal saline, abbreviated as the CIA group), the MTX positive control group (abbreviated as the MTX group), the large dose Artesunate group (at the daily dose of 20 mg/kg), the moderate dose Artesunate group (at the daily dose of 10 mg/ kg), and the small dose of Artesunate group (at the daily dose of 2.5 mg/kg). Mice were sacrificed 7 days of immune injection and their venous blood was collected to obtain the serum. Meanwhile, the synovial tissues of the knee joint were taken by aseptic techniques and primary cultured for 48 h. The supernate was collected by centrifuge. The changes of MCP-1, RANTES, and TNF-alpha in the serum and the synoviocyte culture supernate were observed in each group before and after treatment using ELISA.</p><p><b>RESULTS</b>Artesunate significantly decreased the expressions of TNF-alpha in the serum and the synoviocyte culture supernate, showing significant difference when compared with the model control groups (P < 0.05). There was no statistical difference in the large dose Artesunate group and the moderate dose Artesunate group when compared with the MTX group (P > 0.05). But statistical difference existed in the large dose Artesunate group, the moderate dose Artesunate group, and the MTX group when compared with the small dose Artesunate group (P < 0.05). Artesunate could significantly decrease the expressions of MCP-1 and RANTES in the serum and the synoviocyte culture supernate, showing statistical difference when compared with the model control group (P < 0.05). But no statistical difference existed when compared with the MTX group (P > 0.05).</p><p><b>CONCLUSION</b>The mechanism of anti-inflammatory action and immune regulation of Artesunate might be correlated with the inhibition of inflammatory factor TNF-alpha and chemotactic factors MCP-1 and RANTES.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effects of alpha-linolenic acid (ALA) on inflammation and oxidative stress in the diabetic rats.</p><p><b>METHODS</b>An experimental type 2 diabetes mellitus model was induced by feeding male SD rats with diet of high fat for 4 weeks and then injected them intraperitoneally with streptozocin (STZ) at 30 mg/kg. Then the animals were randomly divided into three groups (n = 10): control group, diabetic group and ALA group. Four weeks later, tumor necrosis factor (TNF)-a, soluble P-selectin (sP-selectin), soluble intercellular adhesion molecule-1 (sICAM-1), nitric oxide (NO) production, malondialdehyde (MDA), superoxide dismutase (SOD) and catalase (CAT) in the serum were determined.</p><p><b>RESULTS</b>Inflammatory agents including TNF-alpha, sP-selectin and sICAM-1 increased in diabetic rats to compare with control group. Treatment with ALA significantly decreased TNF-alpha, sP-selectin and slCAM-1 to compare with diabetic group. Furthermore, compared with control group, serum MDA production increased whereas NO production, SOD and CAT activities decreased in diabetic rats. Treatment with ALA reduced MDA production, increased NO production, promoted SOD and CAT activities compared with diabetic group.</p><p><b>CONCLUSION</b>These results indicate that diet rich in ALA exerted the anti-inflammatory and anti-oxidative effects in diabetic rats, which may be beneficial to the prevention and treatment of diabetes.</p>
